Dell YRDD6 42Wh Laptop Battery

This Dell YRDD6 battery supplies 42Wh at 11.4V using three lithium-ion cells. It is designed as a direct replacement for select Latitude, Inspiron and Vostro notebooks. Buyers needing a factory-spec power source for those models will find it compatible.

Upgrading from a worn original

When an original pack no longer holds a useful charge, this 42Wh unit restores the runtime the laptop was built for. The jump is worth it if the existing battery has degraded below daily needs and the machine itself still meets the user's workload. It is not for buyers who want more storage or builders who need a second card.

Limits of the 11.4V lithium-ion standard

The 11.4V lithium-ion chemistry delivers a fixed energy ceiling of 42Wh in this three-cell format. Runtime scales with the notebook's power draw, so heavy workloads will deplete the pack faster than light use. Capacity cannot be expanded without moving to a higher-capacity pack that the chassis may not accept.

Questions about this item

Will the 3-cell 11.4 V pack fit my Latitude, Inspiron or Vostro chassis?

The battery is built for select Latitude, Inspiron and Vostro laptops; match the YRDD6 part number on your old pack to confirm physical fit.

What is the common mistake when installing the YRDD6 battery?

Forcing the pack before the latch clicks — slide it in until the release lever snaps fully into place.

When should I replace the 42 Wh lithium-ion pack?

Replace it when run-time falls far short of a full charge or the OS flags a permanent capacity loss.
